## Why The memories MCP `read` tool already supports `line_offset`, but it cannot return a bounded line range. That makes it awkward to page through large memory files or request a small slice without relying on token truncation. ## What changed - add an optional `max_lines` parameter to the memories MCP `read` tool schema and request parsing - cap local backend reads to the requested number of lines before token truncation - treat `max_lines = 0` as an invalid request and surface it as `invalid_params` - add backend tests for bounded reads and invalid line request validation ## Testing - added coverage in `memories/mcp/src/local_tests.rs` for `max_lines` reads and invalid `max_lines` / `line_offset` requests
npm i -g @openai/codex
or brew install --cask codex
Codex CLI is a coding agent from OpenAI that runs locally on your computer.
If you want Codex in your code editor (VS Code, Cursor, Windsurf), install in your IDE.
If you want the desktop app experience, run
codex app or visit the Codex App page.
If you are looking for the cloud-based agent from OpenAI, Codex Web, go to chatgpt.com/codex.
Quickstart
Installing and running Codex CLI
Install globally with your preferred package manager:
# Install using npm
npm install -g @openai/codex
# Install using Homebrew
brew install --cask codex
Then simply run codex to get started.
You can also go to the latest GitHub Release and download the appropriate binary for your platform.
Each GitHub Release contains many executables, but in practice, you likely want one of these:
- macOS
- Apple Silicon/arm64:
codex-aarch64-apple-darwin.tar.gz - x86_64 (older Mac hardware):
codex-x86_64-apple-darwin.tar.gz
- Apple Silicon/arm64:
- Linux
- x86_64:
codex-x86_64-unknown-linux-musl.tar.gz - arm64:
codex-aarch64-unknown-linux-musl.tar.gz
- x86_64:
Each archive contains a single entry with the platform baked into the name (e.g., codex-x86_64-unknown-linux-musl), so you likely want to rename it to codex after extracting it.
